“Unique in quality, high pressure and high capacity”

The standard in the cocoa and chocolate industry, Royal Duyvis Wiener’s machines have earned this professional position. Designed and manufactured to fulfill the very highest global industrial demands. A proven example of these innovations are the cocoa liquor, cocoa butter and chocolate pumps.

Even under the most extreme industrial circumstances the Royal Duyvis Wiener pump is able to complete its crucial work. The gear pumps are especially designed for the transportation of demanding viscous and abrasive substances, which require a relatively high pressure up to 25 bar.

The LQP-300-25 and LQP-660-15 are perfectly suitable for the filling of cocoa butter presses. As a result of the high pressure, cocoa butter usually starts to flow during the filling process, so prior to the actual pressing.
